simply essential

be aware that the recent discoveries on the "vitamin" D show that it is extremely important, and that a deficiency can cause unexpected dangerous conditions.

The book does not contain a multitude of notions, do not expect a paved describing tons of things. The principles and the figures are actually simple, but so important that I consider buying this book essential, especially given its price ...

Another advice: ask your doctor dosage 25 (OH) D, reimbursed by the secu, cheap for secu and even dare I say it saves money secu, since among cases deficient enable it to rebalance, removing pathologies, which will make a saving for secu and especially for the person who will be healthier!
